— construction method and t. D.
A separate important part of the design of the engineering infrastructure of the facility includes external engineering networks. Petersburg has construction sites both on the outskirts and in the center of the metropolis. Pipelines are laid under parks and roads in the last century, many of them are outdated physically and morally, so the design of the new engineering network requires a thorough study of archival documentation. Often the connection of built buildings to external networks is possible only after their reconstruction. The reconstruction of the engineering structure is today possible only when using new technologies and materials. So, for laying new pipelines in the center, the GND is used — horizontal directed drilling. This method allows you to pull the pipeline underground without opening the soil. The monitor shows how drilling is going on, there is the opportunity to “get around” the obstacle in the form of an old masonry or other. The use of the GND does not require stopping movement if you need to lay communications under the highway, which is very comfortable for the life of the city.
